ACS712 Current Sensor Module +/- 5A

ACS712 Current Sensor Module

The ACS712 Current Sensor Module, with a 5A range, is equipped with a precise Hall circuit that has a low offset and linear design. Its copper conduction path is strategically placed near the surface of the die. When current flows through this path, it creates a magnetic field that the Hall IC converts into a corresponding voltage.

Monitoring and regulating the flow of current is essential in a vast range of uses, such as over-current protection systems, charging batteries, operating switching mode power supplies, tracking wattage usage digitally, and programming current outputs.

This ACS721 module utilizes the ACS712 sensor to precisely measure both AC and DC currents.

The detected current can reach a maximum of 5A, whether AC or DC, and can be read through the Arduino’s analog I/O port.

Please read the following instructions carefully for proper understanding.
